Quiet Your Ride With Sound Deadening

Installing sound deadening in your classic isn’t a hard job. Having modern sound deadening pays dividends every time you drive the car by making your interior quieter and more comfortable to drive. 

Benefits of Sound Deadener

  1. Reduced Road Noise:

    • Roads can be noisy with grooving and potholes, and the thin metal panels of classic cars offer little insulation. Sound deadener helps dampen vibrations and reduce road noise, creating a quieter cabin for a more enjoyable driving experience.
  2. Enhanced Thermal Insulation:

    • Classic cars are notorious for their limited insulation against external temperatures. Sound deadener not only absorbs noise but also provides thermal insulation, keeping your car cooler in the summer and warmer in the winter.
  3. Improved Audio Quality:

    • If you’re an audiophile or simply enjoy your favorite tunes while cruising, a sound deadener can improve the acoustics within the car. By reducing external noise, you’ll hear clearer and more vibrant sound from your audio system.
  4. Vibration Control:

    • Classic cars often suffer from rattles and vibrations caused by the engine, road conditions, or the exhaust system. Sound deadener adds mass and damping to panels, minimizing vibrations and creating a smoother ride.

Butyl Rubber or Asphalt Sound Deadener?

We’re always looking to save a buck when restoring cars. We’ve also seen the peel-and-stick asphalt at our local home improvement store – so why not use that? There’s a bit of a debate on which one works better, but most people will tell you butyl rubber-based sound deadening is hands down better than any asphalt product. 

First, installation is much easier with a butyl rubber-based product. It conforms to the contours of your floor pan or wherever you put it. Butyl rubber also doesn’t harden and crack or lose adhesion like its asphalt counterparts. Another important factor is asphalt-based will give off odors – nobody wants that!

How Does Sound Deadener Work?

Sound comes from something vibrating. Think of a speaker, it’s a cone that’s vibrating which gives us sound. In our classic cars, a majority of that is from the sheet metal itself vibrating from the engine or driving down the road. 

How sound deadener works is by eliminating or slowing down those vibrations. Think of your floor pan vibrating(even microscopically) when driving. Sound deadening slows down or even eliminates that vibration to allow for a quieter ride. 

In addition to the reduction in vibration, the added rubber acts as a sound insulator to help absorb sound waves resulting in a much quieter car overall. 

Where To Put Sound Deadener?

Simply put, wherever you can! Think about how a sound deadener works, by slowing vibrations. That means just about anywhere you can stick a sound deadener, the better overall it is. Do you need to put it on every square inch possible? No – generally covering a panel with at least 60% sound deadening will help to reduce noise. But if you can cover a section more than that, even better. 

So where should you put sound deadening? For the best bang for the buck, start at the firewall work your way down, and cover the entire floor pan. The roof can also be covered if you don’t have a headliner in. Take off your door panels and apply sound deadening to the backside of the door skins. 

Remember too that your trunk is basically one large metal speaker vibrating down the road. Adding sound deadening to the floor of the trunk, the quarters and even the trunk lid can make a huge improvement. 

Other areas some might not think about are your rear fenderwells. These are transmitting lots of noise from your tires, so cover them as much as possible. Another area is under the hood since that’s one large piece of metal. 

How To Install Sound Deadener

Have you ever used a sticker? Then that’s about how easy it is to apply our Dynamat Sound Deadener! It’s designed to peel-and-stick, just like a sticker. 

Like any job, the first step is preparation. If you have an interior, you’ll need to remove the seats, carpet, and door panels at a minimum. Before you start sticking, take a vacuum and clean up any loose dirt and debris on surfaces. If there’s dirt, then the sound deadener can’t stick which means it can’t do its job. 

One thing you don’t want to do is stick one huge sheet all at once. If there are contours the Dynamat Sound Deadening needs to go on, smaller pieces are easier to work with. Another big thing is after you have stuck the Sound Deadener down, you need to use a roller to apply extra pressure to ensure it’s stuck. A tip is to use the handle end of a screwdriver to push down the edges and middle of the sound deadener. 

While there’s a fair amount of work required to install a Sound Deadener, it’s not a hard job. If you need any Sound Deadener, hop on SS396.com or give our friendly techs a call at (203) 235-1200!
